female looking for quality resources

Hi! My girlfriend is 31 and suffers from hypothyroidism. She is currently taking synthroid and has been tossing the idea of steroid use around for a while since she has a really hard time losing any weight. Right now she's 200 and can't break below this. So, could anyone help us out and point us to some good resources that cover female use while dealing with hypothyroidism, if possible? Appreciate any help we can get. Thanks! Love the site.
